IRAQI JOURNAL OF APPLIED PHYSICS Vol. 22, No. 3, July-September 2026, pp. 433-440 Enhancement of Noor Alhuda H. Hashim 1 Photoluminescence Firas J. Kadhim 2 Characteristics of Dysprosium Tabarak A. Al-Mashhadani 3* Ions in Ag-Dy3+ Co-doped PVA Network College of Pharmacy, 1 Uruk University, In this study, Dy³⁺ doped and Ag- Dy³⁺ embedded Poly vinyl alcohol (PVA) host Baghdad, IRAQ were synthesized at specific concentration of AgNPs and at different 2 Department of Physics, concentration of Dy³⁺ions using chemical method. Spectroscopic analysis of College of Science, silver nanoparticles in such polymer host revealed a distinct Surface Plasmon University of Baghdad, Resonance (SPR) band centered at 426 nm. Absorption and Baghdad, IRAQ photoluminescence (PL) spectra of DyCl3.6H2O in water solution were recorded 3 Institute of Laser for at room temperature, as a function of Dy³⁺ concentration. Prominent emission Postgraduate Studies, bands from Dy³⁺ ions were observed at 4F9/2 → 6H13/2 an
